CLOTHES-FRAME.

Specification of Letters Patent N o. 24,904, dated July 26, 1859.

Y To all whom it may concern:

Be it known that I, JOHN BURR, of Baltimore, State of Maryland, haveinvented a new and useful Improvement in Clothes- Driers; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawing,forming part of this specification, in the several figures of whichsimilar characters of reference denote the same part.

Figure l is a perspective view of the apparatus. Fig. 2 is a verticalsection through axis of shaft. Fig. 3 is a cross section on line as,showing construction of seat.

This invention is designed to obviate many of the defects existing inarticles of this character, by causing the radial arms to bear against aseat which is incapable of rotary motion in itself, while at the sametime the expanded system is free to rotate about the axis of the uprightshaft, without any contact between the said shaft and the lowerconnection of the radial arms, the upright shaft being of polygonalcross section, and the traversing seat so constructed as to be selfretaining at any altitude to which it may be raised.

The details of construction and operation are as follows. The uprightshaft A is of ordinary scantling, though it may be dressed so as to havea polygonal cross section if de sired. Upon the upper extremity of theshaft is attached a cap C, by a pin or other device that will permit thecap to turn upon the head of the shaft. This cap plate is provided withany desired number of lugs a a, around its edge, for the attachment ofthe braces B thereto, so that they will be jointed to the plate C.

The arms D are all connected at bottom to a ring R whose inner diameteris greater than the largest transverse dimension of the shaft A, theconnection being formed by means of lugs Z) o on the periphery of thering to which the arms are attached by bolts, pins or other suitabledevice. The lower extremities of the braces B are connected with thearms D at a suitable point on the arm so as to form joints, and permitthe folding of the apparatus by the descent of the ring, the elevationof the ring R producing the expansion of the system and consequenttightening of the cords E passmg through perforations in the arms D.

The seat S-is made to suit the cross section of the shaft so as to movelongitudinally thereon. It is made up of Vtwo pieces c d u nited by aneye and hook f, and a bolt or. pin passing through two lugs e, whichsaid pin and lugs serve to hold an angular lever Z, hung near its vertexand so constructed that the gravity of the outer arm forces the arm iagainst the upright and causes it to engage a ratchet 7', cut in theshaft or cast and screwed on the face thereof, so that when the seat iselevated upon the shaft, the arm i slips along the ratchet and retainsthe seat in position when the moving force is withdrawn, thusconstituting a self acting detent. By lifting arm 7c, the seat isrendered free to descend. The upper outer edge of the sea-t S is beveledupward, forming a rim with an angular edge u-pon which the ring R rests,an angular groove in the under portion of the ring fitting upon thisrim.

There may be a cavity in the top of the seat for the reception of thering, instead of the rim and groove, though the last named ispreferable. The seat may, if it be desired, be formed of a single pieceinstead of the two parts as represented. The seat, ring, and cap plateare designed to be made of cast metal, the other parts of wood.

The shaft is designed to be fixed in the desired locality; and when notin use the apparatus will be folded. By simply lifting the seat alongthe upright the system is expanded, and when the cords have received theproper tension the moving force has merely to be Withdrawn and the drieris ready for use, the inconvenience of holding the seat with one handwhile with the other the detent is applied, being entirely obviated.

The seat being incapable of rotary movement offers a firm bearing forthe arms, when fixed, the rotation of the movable system having notendency to carry the seat with it and thus strain the detent, asobtains where round shafts and seats capable of rotation are used. Thegroove and rim connection of ring R and seat S permits a free rotationof the arms and parts connected therewith but little friction andWithout wear of the shaft, as is the case where the part to which thearms are attached revolves in contact With the shaft.

The advantages of this construction may be stated as follows. The simpleoperation of lifting the seat is all that is necessary to spread thedrier. A firm bearing, not effected by the rotation of the expandedportion is given to the arms. The rotation of the system is effectedWith the least amount of friction, and Without Wear on the shaft. Andmoreover the construction giving these advantages is more economicalthan Where cylindrical shafts and parts adapted thereto are used.

Having described my invention and the voperation thereof-What I claim asnew and JOHN BURR.
